Key change in mxl in every export

[Blaxzter]

Hello everyone, I have to miss a setting somewhere.
In every single transcription I do, there is a key change on the new line:

This is the input:

And this is the mxl file loaded in muse score:

And also the same happens when transforming to abc notation.

It happens with all the music I tested.

I've looked into the xml file and I see this in the 5th measure:

      <print new-system="yes">
        <system-layout>
          <system-margins>
            <left-margin>1</left-margin>
            <right-margin>2</right-margin>
          </system-margins>
          <system-distance>50</system-distance>
        </system-layout>
      </print>
      <attributes>
        <key>
          <fifths>0</fifths>
        </key>
        <staff-details print-object="yes"></staff-details>
      </attributes>

When I delete that, all following notes of that key will have a natural sign:

Help pls.
I don't know why it does that.

Perhaps, this is due to the lack of any header at the beginning of the second staff.
Could you try to manually insert a treble clef before the key signature?
Just a guess.

I can confirm that the root cause is the lack of standard header at the beginning of second staff.

The real solution would be to feed Audiveris with a legal / standard staff.

A manual workaround is as follows (I just tried it):

1. Remove the starting flat sign (it was not recognized as a key!)
2. Insert a treble clef (drag n' drop from shape palette, ClefsAndShifts set)
3. Insert a 1-flat key (drag n' drop from shape palette, Keys set)

Then export.

Thank you for your help.

As my background in in music isn't so deep I didn't know that the sheet music wasn't legal.

As I have currently 500 sheet music with this layout, (with more coming in) fixing them manually would be a bit tedious.

If there is no flag or option I could use that doesn't allow key changes/ or a different default action on faulty staffs than I'll probably have to talk to the team.
